Feature Configuration Guide for NXP-based Wireless Modules on i.MX 8M Quad EVK
2.6 Configure and test Wi-Fi direct
This section describes the Wi-Fi direct feature which is used to establish a connection
that allows for device-to-device or peer-to-peer communication, linking devices together
without a nearby centralized network.
Use the following steps to test the Wi-Fi direct feature:
• Edit wifi_mod_para_sd8987.conf configuration file to add p2p_enh=1 and
host_mlme=1 parameter-value pairs
root@imx8mqevk:~# nano /lib/firmware/nxp/wifi_mod_para_sd8987.conf
• Updates in the configuration file:
SD8987 = {
cfg80211_wext=0xf
wfd_name=p2p
max_vir_bss=1
cal_data_cfg=none
drv_mode=7
ps_mode=2
auto_ds=2
fw_name=nxp/sdiouart8987_combo_v0.bin
p2p_enh=1
host_mlme=1
}
• Load the modules in the kernel:
root@imx8mqevk:~# modprobe moal mod_para=nxp/wifi_mod_para_sd8987.conf
